Butterworth_low_pass_and_high_pass_filters

HHT工具箱，希尔伯特黄变换用的工具箱和emd程序代码(HHT toolbox, EMD decomposition of essential things, Hilbert-Huang Transform toolbox and program code used emd)

Based on mathematical and physical model to get the simulated I-V curve

33节点的配电网重构程序，基于粒子群算法。相当快速。但是需要再修改源码才可以重新生成数据。(33 node distribution network reconfiguration procedures, based on particle swarm optimization. Pretty fast. But the need to modify the source code before they can re-generate the data.)

雷达辐射源信噪比特性程序，其中包括cw、psk、fsk、lfm、nlfm等几种信号(Radar emitter signal-to-noise ratio of the characteristic procedures, including cw, psk, fsk, lfm, nlfm several signal)

瑞利衰落信道下的MIMO各态历经系统容量仿真(Rayleigh fading channels MIMO ergodic system capacity simulation)

说明：  画n角星,其中n为大于5的奇数(偶数可以看成两个奇数角星的叠加) 比如6角星,可以看成两个三角星的叠加(Plotting and filling n-pointed star, in which n is an odd number greater than 5)

产生一个中频正交的信号，叠加有载频信号，能提出载频并对其解调(Generate an IF quadrature signal, the carrier frequency signal is superimposed, can raise the carrier frequency and demodulating)

说明：  LMS (Least Mean Squares): most basic canonical ANC algo FxLMS (Filtered eXtended Least Mean Squares): adds an additional learned filter for the secondary path signal - signal from cancellation speakers to users ears - to account for phase problems and audio coloration added during practical noise cancellation applications NLMS (Normalized Least Mean Squares): adds simple adaptively updated learning rate on top of LMS to speed convergence. FxNLMS (Normalized Filtered eXtended Least Mean Squares): combines FxLMS and NLMS FuNLMS (Filtered-u Last Mean Squares): adds an additional active LMS filter to FxNLMS to cancel out noise bleeding from the cancellation speaker to the error mic. Fairly robust but convergence not gaurunteed!

用matlab编写了一个，信源产生经过BPSK调制以及根号升余弦滤波器后再加上载波最后将波形图输出的程序(Using matlab prepared a source after BPSK modulation, as well as the square root raised cosine filter and then with the carrier waveform graph output of the program)
